It is of very simple use. It features, big digits, remote button control (with external cable), Lap Time Log file downloadable to your PC.
I am still testing it, but is should work with several WinCE and PocketPC Palm Held machines.It has not yet been tested on the track therefore it is a Beta version.</P>

At the Programs menu call up PocketC Runtime.<br>
Double click on PcceLaTiButton1Beta.
When you want to measure the elapsed lap time push the button.
The lap time data will be saved at the indicated file in My Documet area of you Palm PC.<br>
The Remote button is done thru the serial port by conneting DE9.7 to DE9.6.
This feature has been so far tested only on a Philips Nino 300 (1/15/2001).

The Nino300 Serial port Connector:<br>
The Remote button is done thru the serial port by conneting DE9.7 to DE9.6.
Each WinCE machine has its own serial cable.<br>
A good source for these cables are the internet Auctions.

<P>So far not yet tested on vehicle.<br>
Off board testing has been done only on a Nino300.<br>
The time display doesn't flow with the time. It simply displays the last measured laptime and the current best laptime.
<br>
Current remote triggering is with a button. I have not yet developed, or found a way to trigger the LapTimer remotely from an off board source.<br>
The time data log is messy due o the fact that carriage return "\r" doesn't work. Also new line "\n" doesn't work.
These are PocketC V.2 bugs.Feb/2/2001, they have suggested me a fix for this problem, see PocketC bugs forum.

Test it on my go-karts.<br>
I plan to figure out a way to trigger with an outboard source the laptimer.
<br>
In the far future I hope to go as far as doing some data logging.
